Nadia never did straighten things out with Peter. She really lashed out at him in Avengers #11, the last issue before the Legacy renumbering (she was angry because the team had been evicted from the Baxter Building, which of course, was Spidey's fault). Those last three issues before No Surrender were a crossover with the Champions, ending with Nadia joining the teen team (she was officially on double duty briefly, as No Surrender is actually set after Champions #21). Peter then apparently quit the Avengers before No Surrender started.
